This invention relates in general to that type of washing machine setforth in my United States Patents Nos. 1,285,943 and 1,347,617, andparticularly to new and useful 6 improvements in the construction ofsuch washin machines.

An 0 ject of this invention is to provide a device of the characterwhich embodies a novel feature of construction whereby clothes can bethoroughly and quickly cleansed by mechanical means without inju to eventhe most delicate fabrics.

Lother object of the invention is to provide a washing machine which isextremely quick and thorough in its action and will enable lar equantities of soiled fabrics to be washe in a short duration of time,which can be operated easily, and which has no delicate arts which areliable to break or get out 0 order.

' still further object of the invention is to provide hollow conical shaed means affixed in the interior of a was in machine thereby providingcatching an rubbing 25 means for the washing of soiled'fabrics.

Anotherob'ect of the invention is to provide means 0 separatin the gasesfrom the soapy solution during t e operation of the washing machine.

Other features and advantages of the improved machine will appearclearly from the detailed description given hereinafter and theaccompanying drawin in which the same reference numerals lndicate likean parts throughout the several views, and

Figure 11 is a plan view of Figure 10.

The preferred form of construction as illustrated in the drawingscomprises an outer spherical casing 12 having flat sides 13 and 14. Thisouter casing 12 is rigidly secured 66 to a suitable base 13 of anydesired construction. Extending vupwardly from base 13 are su ports 14and 15, both of which are provi ed with bearing surfaces 16 and 17 forthe shaftings or trunnions 18 and 19 which are inte all formed withsubstantially U-shape hol ing strap 20.

The numerals 21 and 22 designate the two complemental. halves of thehollow inner casing of the washing machine, said casin having thegeneral shape of a flattene sphere so that across section taken in thevertical direction is circular, while a cross section taken at ri htangles thereof is substantially elliptical, as indicated in Figure 2.The curvature portion of the inner casing is provided with transversecorrugations 22 which diminish at the flat sides. The halves of theinner casings 21 and 22 overlap each other at their maximum diameter andare surrounded b a band 23 conforming to the contour o the casing. Atthis overlapping junction the casings 21 and 22 and surrounding band 23are electrically welded together or by any other desirable process,thereby forming a unit casing 23.

n the same manner the Ushaped strap 20 is integrally joined on the outersurface of the inner halves of the casings 21 and 22. These casings 21and 22 are preferably stamped out of flat sheet metal and by providingthe same with said corrugations 22 the spare metal is utilized in thestamping process.

As shown in Figure 4, I provide the trun- 'nion 18 with a gear wheel 23.so that the inner casing 23- may be operated by an electric motor 23-through chain 23 (Fig. 8). With the exception of the gear wheel on oneof the trunnions, a description of the adja cent construction of one ofthe trunnions applies equally as well as to the other, since they areidentical in construction only be ing disposed at opposite sidesrelative to each other on the casing 23. The trunnion is provided withsuitable ring 24% in orde to prevent leakage.

partof themeans for venting the con tents of the inner casing 23 isprovided by havin the opposite sides of the flat portion of sai innercasing 23 turned inwardly at 25' erg in concentric arrangement with thetrunnions l8 and 19. The diameter of each of the circles of the turnedin portion 25 is greater than the width of the overlying strap 20 inorder to allow an opening on the sides of the overlying strap to theinterior of the casing 23*. Concentrically arranged and attached at theflared ends 26 on the opposite inner side of the inner casing 23 is thehousing 27. This housing 27v is provided with a sloping side 28 andperforations 29 on its flat circular surface. Disposed centrally in thehousing is a flat circular disk 30 with an openin 30 in the center of itfor the reception 0 tube 31 connecting with the central portion of 25,thereby permitting a free passage from the interior or casing 23 to theexterior thereof at this elevation. Both inner casing 23 and outercasing 12 are each...

provided with a drain plug 31* and 32 for drainage. Referring nowparticularly to Figure 2, I provide novel means for catching, rubbingand releasing the fabrics to be washed when the machine is in operationby providing the inner casing 23 with a series of pro ecting arms 32,33, 34, 35 and 36, attached by any suitable means at the base to theinner spherical casing. Since these arms are alike in construction adescription of one will apply to all of them. The arm may be made of asingle sheet of metal or two pieces as may be desirable. The arm as alsoshown in Figures 5 and 6 is circular in shape, running smaller graduallyout from the base to the free'end which has a large opening 37 directlyin the center of the end, as well as with circular corrugations 38pressed on the sides thereof. These arms are all set at a slantingangle, 32 and 33 being disposed opposite each other and 34, 35 and 36set at zig-zag relation. with respect to each other.

At the upper portion of the inner casing 23 a door 39 is hinged theretoto, as well as having a washingaarm 4O aifixed in the same manner andconstruction as the other arms, as shown in'Figure 9.

At the upper portion of the outer casing 12 another door 41 of greaterarea than door 39,

Mode of operation.

In the actuation of the washing machine the inner casing 23 rotatesnormally in a counter clockwise direction for washing purposes. Assumingthat there is a quantity oi soiled fabrics placed in this inner casing23 with a soapy solution for cleansing purposes. Upon the initialrotation the fabrics are caught by one of the arms and held for aquarter of a revolution and then begins slipping iirom said arm due tobeing in a soaked condition and at the same time causing said fabrics tobe rubbed. Likewise as this operation is continued the succeeding armscontinue to function in the same manner and thereby quicklyaccomplishing desired results.

' In order to separate the gas pressures from a the cleansing solutionduring the rotation of 4 casing 23 it will be noted that the solution-is caught in the housing 27 thereby allowing the gas to pass out ofopening 30 into tube 31 and then through the perforated door 41. to theatmosphere. Likewise any overflow of the solution passes through 30 31and then into the outer casing 12.

It is contemplated that numerous structural changes may be made in themachine without departing from the scope of the invention, except as thesame may be limited by the appended claims.

What I claim is 1. A washing machine comprising an outer casing; aninner flat spherical washing casing mounted to rotate in said outercasin a plurality of projecting arms aflixed on t e inner sphericalsurface of said washing casing, said projecting arms serving as catchng,rubbing and releasing elements, said nee ae 8 cal lane some of which aredisposed op end hav' a lar openmg' therein, the outer site to eaichother and others set in ziggg surfeces c fi said a rms having circularcorruposition in respect to one another, thereby gations therein,substantiall as described. 10 causing said arms to serve as catching,rub- In te stmony whereof I ave afiixed my hing and releasing elements,said arms being signature.
